摘　　要：用NaOH溶液溶解贻贝、牡蛎和黄鱼,原子吸收法测定其中的Cu、Pb、Cd、Zn、Cr等元素。所测元素含量与标准推荐值基本一致,测定结果的精密度和准确度明显优于传统的酸溶法,满足海洋环境监测中生物体残毒的分析要求。The oyster, sea mussel and yellow-fin tuna were dissolved in NaOH solution, and the five microelements contents including copper, lead, cadmium, zinc and chromium in them were determined by FAAS and GFAAS. It showed that the measured value of these elements were coincident with reference value of standard sample. The method of base-digestion to determinate five mieroelements oyster, sea mussel and yellow-fin tuna, were superior to the method of acid-digestion in accuracy and precision.
